Since the text to Dave & Andy's "Programming Ruby" book is freely
available, is anyone making changes to reflect changes in Ruby 1.8.x?

The RubyGarden wiki lists ChangesToProgrammingRuby at:
http://www.rubygarden.org/ruby?ChangesToProgrammingRuby

Is anyone actually implementing these changes and if so is there a
version online anywhere that reflects these changes?  Maybe there
could be a CVS repository where the text is kept and people could be
allowed to submit updates?

Thoughts?
